If birth control is used correctly you are 99% protected. There is that 1% chance you can get pregnant. I have never known anyone to get preg while on birth control, but I am sure there are some women out there that fall into that 1%.

Its really up to you. If it makes you feel safer then use a condom. I never used a condom while on depo just because I didnt want to.

What do you guys think?

Some people, especially young people (when pregnancy would be a really bad thing) use condoms with their birth control. It will make your protection slightly higher.

It's not necessary, though, as long as you are using the ring correctly.

However, it is a good idea to keep condoms on hand in case you need them- for example, if you are on antibiotics, you should use condoms, or if you're having sex with someone new and you need protection from STD's. I'm married and on the pill but we use condoms from time to time if I miss a pill or throw up or anything like that.

But it's up to you and what you're comfortable with. It's certainly not stupid to use both, it's smart of you to be protecting yourself.
